Fun Activities – Dental Health Teeth Experiment

Materials Needed For the Dental Health Teeth Experiment 1 cup soda or soft drink (a brown soda such as root beer or cola) 4 containers 1 cup vinegar 5 plastic cups or jars 1 cup fruit juice (lemonade, orange juice or apple juice) 1 cup water 1-4 toothbrushes Baking soda or toothpaste 4 hard boiled eggs Paper towel 4 egg holders, optional Process: Start by placing your eggs in your plastic cups or jars. Pour liquids over the egg until they are completely submerged. Make an index card or chart to show which liquids are in which containers. Encourage the children to Hypothesize what will happen to the eggs when left in the liquids. Leave the plastic cups and plates to soak overnight. Observation: The next day, carefully set up the toothbrushes, water, and toothpaste. One at a time, remove an egg from the liquid and place it in an egg holder. Encourage the children to observe and discuss what the liquids have done to the eggs and the color of the egg shells. You will likely see the following results: Soft Drink: A brown color change Juice: A gritty coating on the egg Vinegar: Softening the egg shell Water: A faint smell At this point, try using water to remove the effects of the different liquids. If it doesn't remove the staining and effects, add the toothpaste to get it off. This is a great way to show the power of using toothpaste to clean your teeth. Conclusions: At the end of the experiment, it’s a good idea to ask the children what they remember and what they learned. Encourage them to draw connections between the science experiment and their own lives – for example, asking which drinks are probably better for their teeth, and if you need toothpaste to do a good job of brushing their teeth.
